Dear
Welcome to HCM
We understand your concerns
I went through your details. I suggest you not to worry much. I see you have two problems. One about the public performance and the second about the
chest pain. As the investigations of the chest came negative, then you have nothing to worry (already you are aware). Still you feel the pain. That is
anxiety and thought process. The pain false (imagined by you). this happens due to psychosomatic illness like
hypochondriasis.
Psychotherapy should help you overcome.
Thoughts are there to come and that is the duty of the brain. let the thoughts come. You need to divert the thoughts to more priority ones. Means be busy and divert thoughts. Relaxation and
meditation plays an important role in controlling hypochondriasis. Plenty of water,
oxygen and exercise most important.
Performance anxiety can only be successfully treated with the help of
systematic desensitization. A therapy followed under behavior therapy. This therapy brings back the confidence in you, for sure.
For more psychotherapy techniques, You can post a direct question to me in this website. Include every detail as much as you can. I shall prescribe some psychotherapy techniques to control your condition. I am sure that the techniques should be a success.
Hope this answers your query. Available for further clarifications.
Good luck.
